A central focus of my research investigates how biodiversity is generated and maintained in the Neotropics with a special emphasis on understanding the link between molecules and phenotype. Combining molecular genetics and field biology, I explore evolutionary questions at the levels of populations (speciation-in-action), species (phylogeography and systematics), and apply these data to conservation efforts (conservation genetics).

Several aspects of my research combine specimen-based research and my projects are based on international multidisciplinary collaborations involving local students and communities.
